Letters Patent No. 107,091, dated September 6, 1870.

IMPROVEMENT IN MACHINE POR BORING AND VMARKING.

-Orem The Schednle referred to in these Letters Patent and making` part o! the same To all whom 'it may concern-.-

Be it known that I, Governance M. Nrekasos, of Ellenville, in the county of Ulster and State of New York, have invented a new and improved Gombined Marking and Boring-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled iu the artto make and use the same, reference being had to thevaccompanying drawing forming part of this specification.

Figure l represents a plan or top view of my improved machine for marking and boring. l

Figure 2 is an end elevation, partly in section, of the same.

ASimilar letters of reference indicate corresponding parts.

My invention relates to marking audboring-machines, and consistsV in .certain improvements, which will be -tirst described in connection with other parts necessary to make them clearly understood, and then specified in the claim.

`A in the drawing -represents the frame of my improved machine. It contains the bearings of two horizontal shafts, B O, which are hung in its lower part.

The shaft b receives rotary motionv from suitable machinery,4 and imparts it, by means of a belt, c, to the shaft C.

To the shaft are secured crank-pins, b b, which are, by means of rods c c, connected with a sliding frame, D.

As the shaft G is revolved, the slide D will be moved up and down, according to the stroke of the pins b.

In ears (l, that project from the .slide D, is hung a shaft, E, which is, by belts e. f, connected wtlrthe driving-shaft B, to be revolved thereby.

Upon the shaft E are mounted the marking-points y g, which, by being revolved, mark the article that may be placed against them. The markers receive thus combined rotary and reciprocating motion, and

are thereby enabled to make long marks.

The articlesto be marked are placed upon a transverselyfsliding carriage, F, on which a gauge, h, may be secured. They are then, with said carriage, moved toward the marker, and are marked.

' 1f the markerswould only revolve, tbey'would not 'make but short unreliable lines. By having the up- -aud-down motion, they produce lines of suitable length.

By attaching the belt a, -the rotary motion alone can be obtained for the marker.

Upon the frame A are also set a pair or more of carriages, G G, which can be adjusted on and are supported by longitudinal rails, t t, of the frame.

Each carriage G supports. a transverse shaft, H,

that receives rotaryumotiouvby a belt, j, from the.

shaft B.

In each shaft H is secured a boring-bit, o.

'lhe bits can, with their carriages, beset any suitable distance apart, and held secured in the same by set-screws, l.

The articles which have been marked are placed upon a transverse slide, AI, which may also have'a gauge, m., and are, on the same, carried toward the bits, to be perforated by the same at the exact desired places. n

The slide I may, it' desired, be made vertically adjustable;

The belts j pass overa long drum or pulley, n, to allow for their adj nstment at their upper ends.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- 1. The marker E, hung on a. slide, D, to receive bothrotary and reciprocating motion, as set forth.

2. The arrangement, upon the frame A, of the slide I between two or more boringtools and a series of marking-tools, as and for the purpose specified.
